The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in ...

Polaron formation in perovskite solar cells has been indicated in scientific research as a possible factor for making this kind of cell particularly efficient, although the mechanism behind ...

Kunyan Zhang, Doctoral Alumna and Study First Author, Rice University A polaron emerges when charge-carrying particles, like electrons, interact with vibrations in a material's atomic or molecular ...

Using first-principles calculations, the authors introduce an alternative mechanism for polaron formation in WO3 termed the anti-distortive polaron that arises from the undoing of inherent ...
